Operation
6.2 Checking operation How to check the pump unit during operation:
1.
Make sure that the differential pressure is at least 1 - 1,5 bar.
2.
Check the pump unit for excessing power consumption, vibrations, increased temperature and leakages. ⮫ Further
information on page 61 🡆 The vibration level must not exceed 4.5 mm/s (rms) continuously or 7.1 mm/s (rms) during the transition states
(guide values).
🡆 The sound pressure level must not exceed the values in the “Technical data” chapter. ⮫ Appendix A ‘Technical data’
on page 69
3.
Check the shaft seal for leakages.
4.
Carry out a visual inspection of the pump unit at least once a month. ⮫ ‘How to visually inspect the pump unit:’ on page 61
5.
Check the operating data (total delivery pressure, delivery rate, viscosity, temperature, speed, power consumption,
etc.). ⮫ Appendix A ‘Technical data’ on page 69
6.
Check the set valve pressure. ⮫ Chapter 9.9 ‘Test the pressure relief valve’ on page 62
6.3 Check the suction-side pressure How to test the suction-side pressure:
Use the pressure sensor installed in the system to check the suction side pressure. Note the information in the Technical
data. ⮫ Appendix A ‘Technical data’ on page 69
6.4 Test the overflow valve How to check the overflow valve:
Check the system pressure using the overflow valve installed in the system. Note the information in the Technical data.
